Abstract:
A lithium secondary battery is disclosed which includes a cathode having a first cathode region and a second cathode region adjacent to the first cathode region, wherein the second cathode region is adjacent to an uncoated region of the cathode substrate; an anode, the anode having a first anode region and a second anode region adjacent to the first anode region, wherein the second anode region is adjacent to an uncoated region of the anode substrate, wherein a value C1 is a ratio of a direct current resistance value RA1 of the first anode region to a direct current resistance value RC1 of the first cathode region; wherein a value C2 is a ratio of a direct current resistance value RA2 of the second anode region to a direct current resistance value RC2 of the second cathode region; and wherein C2
